TELEPHONE MUFFLER.

Application filed March 25,1922. Serial No. sea-lee.

To all whom it may concern:

Be it known that I, J OHN D'. Tom), a citi: zen of the United States, residing at McKenzie, in the county of Carroll and State of Tennessee, have invented a new and useful Telephone Mufiier, of which thQfOllOWlHg is a specification. I

This invention relates to sound deadening devices or mutes, the primary object of the invention being to provide a device of this character for use in connection with the alarm bells of a telephone or the like. A further object of the invention is to provide a device of this character which may be positioned in proximity to the tapper employed for sounding the bell, novel means being provided to be moved to a position be tween the bells and tapper, so that movement of the tapper Wlll be. transmitted through a suitable sound deadening device.

Another object of the invention is the provision or" a mute which may be readily and easily thrown into and out of operation at the will of the operator.

With the foregoing and other objects in View which will appear as the description pro ceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter, described and claimed, it being understood that changes in the precise embodiment of the in-' vention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

' Referring to the drawing 2-- Figure 1 is an elevational view disclosing a device constructed in accordance with the present invention as in its active position.

Figure 2 is an end elevational view of a telephone coil box disclosing the invention as associated with the bells thereof.

Figure 3 is an enlarged elevational view of the device, the same being shown in dotted lines in its inactive position.

Figure 4L is a plan view of the device.

Figure 5 is a longitudinal sectional view through the device.

Referring to the drawing in detail, the device includes a body portion 5, having a curved section 6 adapted to lie directly over the tapper of a telephone bell, when the device has been positioned.

This body portion. 5 also includes forwardly extending spaced arms 7 and rearwardly extending spaced arms 8, the rearwardly extending arms 8 being formed with out out portions 9. Positioned over the cut out portions 9 are sections of soft leather material indicated at 10,- portions of the arms extending inwardly as at 11 to embrace the ends of the leather material 10 to secure the same to the arms 8. These leather sections 10 lie in positions to be engaged by the tapper employed, in sounding the bells, which in the present showing are indicated at 12, so that the sound will be deadened and the alarm will be in the form of a buzzing noise, deadening the vibrations of the the supporting section, and is provided with an opening to accommodate a suitable securmg means, a rearwardlyextendmg ear being also formed at 17 to accommodate a suit I able securing means, whereby the supporting gection may be secured to a telephone bell It might be further stated that the width of the body portion and supporting section is equal 'to the distance between the ordinary alarm bells of a telephone, to permit the device to be readily and easily positioned therebetween.

In the use of the device, if it is desired to move the body portion to its active position, it is only necessary to swing the same downwardly from the position as indicated by Figure 3 of the drawing, as shown in dotted lines, to the position as shown in full lines. Thus it will be seen that the leather sections 10 are brought directly opposite to the tapper, to the end that the tapper does not contact with the bells proper, but engages the leather sections. It follows that the sound is deadened, but, is sufficient to give the necessary alarm. When it is desired to permit the tapper to contact directly with the bells,

s Figure 3 of the drawing.

j Having thus described the invention, what is claimed as new 1s a 1. In combination with the bells and tap per of a telephone signal box, a sound dead ening device comprising a body portion adapted to be positioned between the bells, and means carried by the body portion and adapted to be engaged by the tapper, to restrict vibrations of the bells.

2. In combination with the bells and tapper of a telephone sound box pivoted means disposed between the bells'and adapted to lie Within the path of travel ofthe tapper for restricting movement of the tapper. I

3. In combination with the bells and tapper of atelephone sound box, e sound deadening device comprising" a supporting element adapted to be secured a position directly over a ta'ippeiy-a pivoted" body portion carried by the supportingele'rnent, and saiid body portion carrying strips of leather adapted to lie Withinthe' path of travel of the tapper in its movement towards the bells.

In testimony that I claim the foregoing as my own, I have hereto eflixed my signature in the presence of tvvo Witnesses.
